Lotus still favourite despite double DRS decision

Lotus may have chosen not to race its double DRS at Spa, but Mark Hughes reckons Kimi Raikkonen will still be the man to beat whatever configuration his car is in

The layout of Spa is perfect for maximising the benefit of Lotus's new double-DRS drag-reduction system. But the nature of Spa leaves the team in a horrible dilemma, as the notoriously capricious weather of the region rained both Friday practice sessions out, leaving the team unable to assess the new component.

Sources in the team believe the rear-wing-stalling device – tried out in practice but not raced in the previous two events – could be worth as much as 0.5s around the long Belgian track. But it's crucially important that the team is able to fine-tune the threshold at which the air pressure switches the airflow.
